Protection Guard for Grinding
Place the protection guard 6 onto
the spindle collar of the machine
until the encoding keys of the pro-
tection guard agree with the spin-
dle collar. Press and hold the re-
lease lever 1 while doing this.
Press the protection guard 6 onto
the spindle collar until the shoul-
der of the protection guard is
seated against the flange of the
machine, and turn the protection
guard until it can clearly be heard
to engage.
Adjust the position of the protec-
tion guard 6 to the requirements
of the work process. For this, press the release lever 1 up-
ward and turn the protection guard 6 to the required position.
 Always adjust the protection guard 6 in such a manner
that all 3 red cams of release lever 1 engage into the
corresponding notches of the protection guard 6.
 Adjust the protection guard 6 in such a manner that
sparking is prevented in the direction of the operator.
 The protection guard 6 may be turned only upon actua-
tion of the release lever 1! Otherwise the power tool
may not continue to be used under any circumstances
and must be taken to an after-sales service agent.
Note: The encoding keys on the protection guard 6 ensure
that only a protection guard that fits the machine type can be
mounted.
Protection Guard for Cutting
 For cutting with bonded abrasives, always use the pro-
tection guard for cutting 10.
 Provide for sufficient dust extraction when cutting
stone.
The protection guard for cutting 10 is mounted in the same
manner as the protection guard for grinding 6.
Cutting Guide with Dust Extraction Protection Guard
The cutting guide with dust extraction protection guard 17 is
mounted in the same manner as the protection guard for
grinding 6.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 4.
Screw the auxiliary handle 4 on the right or left of the machine
head depending on the working method.
Hand Guard
 For operations with the rubber sanding plate 13 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 12.
The hand guard 12 is fastened with the auxiliary handle 4.
Bosch Power Tools
Mounting the Grinding Tools
 Before any work on the machine itself, pull the mains
plug.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Clean the grinder spindle 5 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 2.
 Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come damaged.
Grinding/Cutting Disc
Pay attention to the dimensions of the grinding tools. The
mounting hole diameter must fit the mounting flange without
play. Do not use reducers or adapters.
When using diamond cutting discs, pay attention that the di-
rection-of-rotation arrow on the diamond cutting disc and the
direction of rotation of the machine (see direction-of-rotation
arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on the clamping nut
9 and tighten with the two-hole spanner.
 After mounting the grinding tool and before switching
on, check that the grinding tool is correctly mounted
and that it can turn freely. Make sure that the grinding
tool does not graze against the protection guard or oth-
er parts.
Flap Disc
 For operations with the flap disc, always mount the
hand guard 12.
Rubber Sanding Plate
 For operations with the rubber sanding plate 13, al-
ways mount the hand guard 12.
See graphics page for the mounting sequence.
Screw on the round nut 15 and tighten with the two-pin span-
ner.
Cup Brush/Disc Brush
 For operations with the cup brush/wheel brush, always
mount the hand guard 12.
See graphics page for the mounting sequence.
The cup brush/disc brush must be able to be screwed onto
the grinder spindle until it rests firmly against the grinder
spindle flange at the end of the grinder spindle threads. Tight-
en the cup brush/disc brush with an open-end spanner.
